Yes, Android Q is already in Google's works, but the company is also developing the operating system that will replace Android at some point in this year. Cold Fuchsia, although it may not be the last name when it starts, the operating system that would work on smartphones, tablets, laptops and other smart devices, shown in various reports so far. More recently, we learned that Huawei is involved in testing Fuchsia, a sign that developments are moving well together. Another report confirming Google is serious about the new operating system, saying that Fuchsia was available on screen for a special Bluetooth special interest group (SIG) event recently.
Bluetooth SIG, the body that controls Bluetooth certification, hosts three UnPlugFest UPF) events every year, all at different locations, 9to5Google reports. Engineers from different companies have the opportunity to meet and test their devices on these events, and Google brought Fuchsia OS to the UPF event in Berlin in late October to test Fuchsia and Android connectivity.
A Fuchsia engineer confirmed on Twitter explains the team's intention to test Fuchsia at the event, 9to5Google and UPF was mentioned in commitments to Fuchsia Gerrit, which was posted since the event ended, but Also in Android's Gerrit:  In a new commitment published [on Tuesday] to Android's Gerrit Source Code Management, we found our first clue to what might have been on the screen. The obligation itself includes some enhancements to the "Android Comms Test Suite" (or ACTS) to improve Bluetooth compatibility with Fuchsia devices. The connection message shows the test used to confirm the new code's functionality as an UPF test event.
Although it is unclear which devices Google used to run Fuchsia and test Bluetooth connectivity, we've seen OS boot on different devices in the past, with gadgets like Pixelbook and Home Hub that have Bluetooth support in Fuchsia.
